' Patented Nov. 3, 1908,

Original application filed September-'19, 1906, Serial No. 335,176. Divided and this application filed November 11,

' 1907. Serial No. 401,571.

To all whom it may concern:

Be it known that I, CHARLES CUNo, a States, residing at Meriden, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Binding-Posts, of which the following is a full, clear, and exact description.

My invention relates to' improvements in attaching devices, for example, electrical terminal connections or binding posts.

This application is a division from n1 Serial No. 335,176, filed September 19, 1906.

The object of the invention is to provide simple and effective means for two parts to be nected, for example, a wire to be quickly secured to a terminal, the securing means being such that when the parts are set up, dislodgment and the danger of accidental disengagement of the wire is prevented.

In the drawings Figure l is a side elevation of my invention as in operation and in the form of a binding post; Fig. 2 is a side elevation of the same partly in section; Fig. 3 is an end view of a detail; Fig. 4 is a side elevation thereof; Fig. 5' is a view of one of another detail showing the end of a wire; Fig. 6 is an edge view of the detail shown in? Fig. 5, looking from left to right, the wire being removed.

1 represents a screw threaded body or support niolnited on a suitable base 1*, which forms an abutment or shoulder. I

2 represents a wire to be connected to the body 1.

3 is a nut screwthreaded on the body 1.

3 3* are forwardly projecting clutch jaws, the ends of which are tapered, as indicated in Figs. 2, 3 and 4c.

4 is a washer slidable on the body 1. This washer has a beveled entrance at one side arranged to receive the beveled ends of the jaws 3 3 (see Fig. 2). At the opposite side this washer is preferably provided with a curved or annular groove (as best seen in Fig. 5), in which the curved portion or bent end of wire 2 may lie.

4 is a lateral recess in the outer wall of washer & intersecting the said groove, and provided to afford clearance for the wire. One or more of these recesses 4 may be properinitting I quickly and securely' con- I vided, but two are preferable where the wire than fingerpower to securely bind the parts together and v prevent accidental displacethe washer 4 to a position where theresistance of the abutment isencOuntered. When the washer can mqve'no farther, the jaws 3 3 contract by engaging with the incline connection is thus made withoutjamming or weakening the wire or any ofthe parts.

What I claim is 1. In a device of the character described, a threaded body, a nut screw threaded thereon, a washer having a curved groove son one side intersected-bya lateral recess at the outer edge of. the washer, an abutment facing said groove, said nut cooperating with said washer to move the same toward said abutment, and clutch jaws between the washer and nut arranged to cooperate therewith.

2. In a' device of the character described, a threaded body, a nut screw threaded thereon, a washerhaving a curved groove on one side intersected by a lateral recess at the outer edge thereof, an abutmentfacing said groove, said nut cooperating with said washer to move the same toward said abutment, clutch jaws on the nut engaging said washer, and an incline on the latter to force said jaws into binding engagement on said threaded body.

3. In a device of the character described, a threaded body, a nut screw threaded thereon, a washer having a curved groove on outer edge thereof, an abutment facing said washer to move the same toward said abutment, clutch jaws carried by said nut and havin tapered ends, a tapered entrance at the si e of the washer facing said jaws and nection is to be made it requires no morement. In operation the jaws 3 3" first move and frictionally olutc the part 1. A'secure one side intersected by a lateral recess at the groove, said nut cooperating with said washer and: contract as arranged to receive the same. and force them into binding: engagement with said support. 4. In a, bindin'g'post ineluding a'xthreaded terminal having anabutment thereon, a

' washer movable on said'terminal', a taperedentrance at one: sideofs sald washer, a nut aws movable therewith and arranged: to cooperate with the tapered. entranceef said thenuti ismoved towardsaidwasher; v 1

5. In a, finding post, a threaded terminal having an abntment'tliereon, a Washer movable on said terminal and having a tapered Central seat in'its face opposite said abutment, and a leek nut hzwing;- aplit tapered? tapered seat; on the other shank adapted to the tapered central. seat in said Washer.

6. In a device of the character described,

a threaded. body, an abutment thereon, a washer movable on said body; a screwthreaded nut movable on said jaws carried'by one of said movable parts, a

receive said'qawsand press them into hind-- 111g engagement with said body.
